Installing the Memory
The IB831 board supports one DDR3 memory socket for a maximum
total memory of 2GB in DDR3 memory type.
Installing and Removing Memory Modules
To install the DDR3 modules, locate the memory slot on the board and
perform the following steps:
1. Hold the DDR3 module so that the key of the DDR3 module aligns
with those on the memory slot.
2. Gently push the DDR3 module in an upright position until the clips of
the slot close to hold the DDR3 module in place when the DDR3
module touches the bottom of the slot.
3. To remove the DDR3 module, press the clips with both hands.

Bypass and WDT
The bypass function is used to link (or short) two independent Ethernet
ports when user’s application software halts or when power is off.

Communication States:
There are two communications states for the bypass function: (1) Normal
State, (2) Bypass State. A watchdog timer (WDT) or a GPIO are used to
control and switch the communication between the two states.
The block diagram in the section above shows the Normal State, where
the two Ethernet ports work independently. The following diagram shows
the Bypass State, where the two Ethernet ports are bypassed.

Watchdog Timer Configuration
The WDT is used to generate a variety of output signals after a user
programmable count. The WDT is suitable for use in the prevention of
system lock-up, such as when software becomes trapped in a deadlock.
Under these sort of circumstances, the timer will count to zero and the
selected outputs will be driven. Under normal circumstance, the user will
restart the WDT at regular intervals before the timer counts to zero.
